摘要 作者首次采用缓慢自然复温的方法,对异体骨进行冷冻干燥,通过X线片和组织学方法了解其骨缺损修复能力,并与自体骨和新鲜异体骨对比,结果显示,冷冻干燥异体骨骨缺损修复能力与自体骨相比性差异(P>0.05),新鲜异体骨与自体骨相比3周时无显著性差异(P>0.05),8周时有显著异(P<0.05),可能与免疫潜伏期有关。 AbstractThere were many methods to preserve allogeneicbone allograft,however,a lot of studies have shownthat the freeze-dried bone allograft banking is the bestone. But it is not clear what temperature to lyophilizethe allograft is better. In this experiment, we usedmethod,in which the temperature of lyophilization wasraising naturally and regularly,to lyophilize the al-lograft. The repairing ability of the freeze-dried al-lograft was studied in rabbits and comparison wasmade with that of autograft and fresh allograft. Theresults indicated that the repairing ability of bone de-fects was not significantly different between autograftand freeze-dried allograft. There was no significant dif-ferenc between autograft and fresh allograft 3 weeksafter transplantation, but significant difference wasnoted 8 weeks after grafting. It is suggested that thismight be associated with the latent period before im-munological rejection and the method itself, in whichthe temperat ure of lyophilization raising naturally isbeneficial
